Specification of Letters Patent.

Application filed Ju1y 11, 1912. Serial No. 708,903.

To all whom it may concern:

Be it known that I, JOHN WILLIAM AN- nnnson, a citizen of the Dominionof Canada, residing at 222 King street west, in the city of Hamilton, inthe county of WVentworth in the Province of Ontario, Dominion of Canada,have invented certain new and useful Improvements in Trolley- Wheels, ofwhich the following is a specification.

My invention relates to trolley-wheels for electric railroads of theclass formed of several sections, which may be readily disengaged onefrom the other to permit of the insertion of the tread, which treadwears away very rapidly and thereby renders the wheel useless in a shorttime.

One object of my invention is to furnish a trolley-wheel of the abovereferred to class which is provided with oiling means arranged for thecontinuous circulation of oil to the bearings as well as to preventdrip- A still further object of my invention is to so construct thetrolley wheel that it may be readily separated into halves to permit theeasy removal and replacement of the tread when worn out.

With the above and other objects in View, my invention consists in thenovel construction, combination, and arrangement of parts hereinaftermore fully described, and specifically pointed out in the appendedclaim.

In describing my invention in detail, reference is had to theaccompanying sheet of drawings, forming a part of this specification,and wherein like numerals of reference designate like parts throughoutthe description.

Figure 1, is an axial longitudinal section a through a trolley-wheel forelectric railroads incorporating my present improvements. Fig. 2, is aside elevation of the same.

According to the form of my invention illustrated, the trolley-wheelbriefly co1nprises side sections, 1, 1, a removable tread ortrolley-wheel proper 2, and a hollow axle 3, for fitment to the fork ofthe trolley head. The hollow axle 3, is furnished with orifices 4, 4:,and each side section 1, consists of a dished or hollow sheet steelbuilt up receptacle adapted to contain a supply of oil conveniently fedthereinto through oilvalves 5, 5. These side sections are freelyrevoluble on the hub extensions 6, 6, of the trolley wheel proper 2, andsaid hub extensions are pierced with radial holes 7, 7.

8, 8, are oil rings located in the side sections 1, 1, for the purposeof lifting the oil constantly to the respective bearings.

The trolley wheel proper is preferably formed with a solid web portion9, and the tread thereof is shaped on its peripheral faces, 10, 10, tofit snugly to the contour of the side sections 1, 1. Grooves are cut inthe surface of the hub extensions 6, 6, to insure a proper flow of thelubricating oil.

From the foregoing description it will be seen that by my invention Iprovide a very effective and simple trolley-wheel furnished with perfectlubrication.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is:

A trolley Wheel of the character described, comprising in combination, acentral body member having a flaring grooved tread portion, a tubularbearing portion and a re duced central web extending between said treadportion, and said bearing portion, said bearing portion being providedwith a pair of separate peripheral oil grooves one upon each side ofsaid web, hollow lubricant reservoirs disposed upon the opposite sidesof said Web and revolubly mounted upon said tubular body portion, eachof said reservoirs comprising inner and outer walls having theirperipheral edges interengaged, and a bearing portion which embraces thatportion of the bearing portion in which the peripheral oil groove isformed and the inner walls of said lubricant reservoirs being bowed andextending inwardly beneath the tread portion and lylng in contact withthe web at the juncture of said web with said bearing portion, saidlubricant reservoirs aflixed my signature, in the presence of tvyoextending beyond the tread portion and lysubscribing Witnesses, atHamilton, Ontario, ing close thereto and forming trolley Wire Canada,this 24th day of June, A.
